为了从生物力学上比较单独的Bankart损伤修复和Bankart损伤修复联合冈下肌囊腱固定术（A >）在治疗Bankart和Hill-Sachs联合损伤中的作用，对7对（左右）尸体肩进行了测试，首先没有任何损伤，然后进行了Bankart和Hill-Sachs联合损伤。对于每一对，然后将标本随机分配为一侧单独进行Bankart损伤修复或另一侧进行Bankart损伤修复联合修复。在测试过程中，将肩关节置于90 A外展度和最大外旋度，并记录该值。然后在肱骨近端施加50 N的后前向载荷，根据获得的载荷-位移曲线计算关节刚度，Bankart和Hill-Sachs损伤与完整关节相比显著降低关节刚度（p < 0.05）。单独的Bankart损伤修复不能将刚度恢复到完整的水平，而将remplissage添加到Bankart损伤修复中则可以。Bankart和Hill-Sachs损伤后外旋明显增加; Bankart修复使外旋恢复到完整的水平，而与完整和单独Bankart损伤修复相比，与Remplissage相关的Bankart损伤修复显著降低了外旋。与单独Bankart损伤修复相反，与remplissage相关的Bankart损伤修复恢复了完整的关节僵硬。这种刚度的增加与外旋的减少有关。
To biomechanically compare Bankart lesion repair alone and Bankart lesion repair associated with infraspinatus capsulotenodesis described as A >, in the treatment of combined Bankart and Hill-Sachs lesions.Seven pairs (right and left) of cadaveric shoulders have been tested, first without any lesion and then after performing a combined Bankart and Hill-Sachs lesions. For each pair, the specimens were then randomly assigned for Bankart lesion repair alone on one side or for Bankart lesion repair associated with remplissage on the other side. During tests, the shoulder was placed at 90A degrees of abduction and at maximal external rotation, which value was recorded. A 50 N postero-anterior load was then applied to the proximal humerus, and the stiffness was calculated from the obtained load-displacement curve.Bankart and Hill-Sachs lesions significantly (p < 0.05) decreased joint stiffness compared with intact joint. Bankart lesion repair alone did not restore stiffness to the level of intact, while adding the remplissage to the Bankart lesion repair did. External rotation was significantly increased after creation of the Bankart and Hill-Sachs lesion; Bankart repair restored the external rotation to the level of intact, while Bankart lesion repair associated with remplissage significantly decreased external rotation compared with intact and to Bankart lesion repair alone.In cadaveric shoulders with combined Bankart and Hill-Sachs lesions, Bankart lesion repair associated with remplissage restored intact joint stiffness contrary to Bankart lesion repair alone. This increase in stiffness was associated with a decrease in external rotation.
